Web21 mrt. 2024 · The physical process in which a substance tends to spread steadily from regions of high concentration to regions of lower concentration is called diffusion. Diffusion can therefore be considered a macroscopic manifestation of Brownian motion on the microscopic level. Web20 nov. 2024 · Diffusion is a phenomenon that occurs in gases, liquids, and solids. As the temperature of the dispersing substance rises, so does the rate of diffusion. In gases, diffusion is the fastest, whereas in solids, it is the slowest. Various gases have different diffusion rates. Denser gases intermingle at a slower rate than lighter gases.
Scientists Slow Down Speed of Light - ABC News
WebLight travels slowest in Answer: A) Glass Explanation: Because the refractive index of glass is highest, light travels slowly in Glass. We know that the speed of light depends on the refraction index. The higher the index of refraction is, the slower the speed of light is. R.I of air and vacuum = 0 (air is a teeny bit more but can be taken as 0) WebThe simplest picture is that light always travels at the speed of light.
